Pollinators health

Pathogens, viruses in particular, are a main threat to wild and managed pollinator populations worldwide. Our studies focus on mapping patterns of virus prevalence in bee communities, exploring intra- and inter-specific transmission of viruses in these communities, and elucidating the underlying mechanisms. We study the effects of virus infection on bee survival and behavior, and possible implication for the delivery of pollination services.
